Assume, you have 2,00,000 in your ledger and you are an Intraday trader willing to trade in NFO, MCX, CDS, and Cash segments. You want to trade in Nifty, Crudeoil, USDINR, and stocks in the Cash segment. Nifty Intraday margin after Peak margin is 40000/-. CrudeOil Intraday margin after Peak margin is 90000/-. USDINR Intraday margin after Peak margin is 500/-. SBIN Intraday margin after Peak margin is 30/- and you are trading in 1000 qty. This all includes a margin of 1,60,500/- and you will have a free margin of 39500/-(40000+90000+500+30000=160500). With this, you can trade again in any segment where the peak margin requirement is under 39500/-.
